+# 模型测试请求编号修复验收
+
+日期：2026-10-14。范围：AI 模型管理面板点击测试时的浏览器请求编号生成和提交前错误提示。
+
+## 修复
+
+- 使用浏览器原生 `crypto.getRandomValues()` 生成 UUID v4，兼容 HTTPS 和内网 HTTP；无新增依赖，不使用时间戳或 `Math.random()`。
+- 编号生成失败时明确提示“测试尚未提交”，不发送测试请求，不创建未知提交记录，不误导管理员核查未发生的模型调用。
+- 请求发出后的中断核查、联合测试、按用途开放和服务端超级管理员限制沿用现有流程。
+
+## 验证证据
+
+- 隔离发布预览来自 `21b6eb767c9fb1d140e69d763399381eb308d770` 的 Git 存档，仅覆盖本次修复；未混入详情页知识库等工作区改动。
+- 13 个相关测试文件、245 项测试全部通过，涵盖 UUID 格式与唯一性、版本和变体位、缺少安全随机数时拒绝提交、恢复后重试、异常核查和服务端权限。
+- 独立 HTTP 测试页由浏览器实际运行同一份 `lib/browser-uuid.ts` 转译代码。原生结果：`isSecureContext=false`、`crypto.randomUUID=undefined`、`crypto.getRandomValues=function`；100 个编号全部符合 UUID v4，且互不重复。无登录、密钥或模型调用。
+- HTTP 测试源码的 LF 规范化 SHA-256：`ba99717287a1d1c372871867ff0e56df5aa4090e5b02f1f32637d5153dcd9d4e`。
+- 本地隔离账号通过页面实际点击 Gemini `gemini-3-flash` 联合测试，分析、文案均通过；新增一次上游调用；相同请求编号再次提交没有新增调用。
+- 上游请求编号：`23e9e874-8383-4ded-8198-3e94ba13db6c`；联合执行编号：`a736553d-486f-4680-a458-0507671c2b86`。生产模型测试记录未改动。
+- 桌面 1440px、手机 390px 无横向溢出；确认、取消和完成状态正常，手机端取消未调用模型。截图保存在忽略目录 `output/ai-browser-uuid-20261014/`。
+
+## Impeccable 范围审查
+
+Operate 模式，保留现有界面。范围评分 19/20：可访问性 3、性能 4、响应式 4、主题一致性 4、实现完整性 4。新增错误提示使用现有 `role=alert`；不新增样式、动画、依赖或权限入口。面板检测器结果为 0 项，不代表整个管理后台完成全面 WCAG 审计。
+
+## 限制与发布核对
+
+浏览器自动化对 HTTP 别名地址的 DOM/截图读取超时；独立测试页的浏览器原生回执已收取，管理面板实际点击在本地回环地址完成。不能据此宣称已在生产 HTTP 页面实际点击模型。
+
+发布使用干净的 Git 提交构建 Linux 镜像，无数据库迁移。上线后核对部署提交、健康检查、普通用户拒绝访问、模型配置与验证记录不变；生产验收不额外调用模型。上一版本镜像保留用于回滚，当前镜像传输包在校验后清理。
